WATER-QLQSET-FLUSHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 545,566, dated September 3, 1895. Application filed March 1, 1895. Serial No. 540,199. (No model.)

To all whom it may concern:

Be it known that 1, JOHN RIGLEY, a citizen of the United States, residing in Elmira, Ohemung county, State of New York, have invented certain new and useful Improvements in XVater-Closet-Flushing Apparatus; and I do hereby declare the following to be a full, clear, and exact description. of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part 0 this specification.

The object of this invention is to provide a flushing device for water-closets of simple, strong, and durable construction, reliable in operation, and by meansof which device the gurgling noise during and after the operation of flushing is fully avoided. The invention consists in the improved flushing device, its siphon, and automatlcally-controlled air-valve, and in the combination and arrangement of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a central sectional view.

of my improved device, specially applicable to water-closets where a continuous flushing is required while the said closet is in use.

. 4', certain portions being shown in section and Fig. 2 is a central sectional view illustrating a modified form adapted for public buildings. Figs. 3 and 3 are detail views of an ordinary siphon-pipe provided with my improved airvalve. Fig. is an enlarged detail view or" the air-valve detached; Fig. 4, a central sectional View of another modified form of the flushing device; Fig. 5, an end view of Fi others broken away; and Fig. 6, a detail view illustrating my improved air-valve adapted to a cone siphon of ordinary construction.

In said drawings, a and I) represent the lower and upper tanks, respectively communicating with each other through pipe (1 and also through the overflow-pipe e, as clearly shown. On the under side of the lower tank a is secured in any desired manner, or made integral therewith, a chamber or receptacle h, the sides of which form the bearings for the horizontally-arranged shaft '6, on which is fulcrumed the bucket j with pointed mouth it. To the bottom of the chamber h is secured the flushing-pipe m, entering the bowl of the water-closet n in theusual manner. Penetrating the bottom of the lower tank a and arranged with its outlet above the bucket j is a drip-pipe f, provided with a regulating-cock g. If preferred, said drip-pipe f can penetrate the side of the tank Ct and also the side of the receptacle h, in which case the regulating-cock g is arranged on the exposed portion of said drip-pipe f, as clearly shown'in Figs. 4 and 5. In the lower tank a is also socured a substantially U-shaped siphon-pipe 7', extending with one end into the receptacle h, while its other end extends downward toward and near the bottom of the tank, and is by preference provided with a daring mouthpiece s,'Fig. 1. To the top of the siphon-pipe r or to one of its sides is secured an air-pipe u, terminating in a valve-seat controlled by a valve 0;, arranged on the counterbalanced arm to, pivoted, as at o, to a bracket on the siphon-pipe. To the opposite end of arm/w .is fixed a chain 1 connected to a hollow ball .2, adapted to be moved up and down by the rising and falling of the water in the tank,

and by preference guided on the rod 5'.

in Fig. 4 of thedrawings the siphon-pipe r is covered by a cone a", secured by means of a spider or in any desired manner to thetop of the said siphon-pipe 0' and extends downward to near the bottom of the tank. The ball or float is secured to one end of arm .2 the other end of which is pivoted to the cone, as clearly shown in the drawings. The water is supplied to the tank I (or a) by means of v the ordinary supply-pipe 0, provided with a stop-cock c. The supply-pipe may also be provided with a valve 0 and handle 1), controlled by the water-closet seat in the usual manner, but this connection is only used where a continuous flushing during the usage of the water-closet is wanted.

In Fig. 6 is illustrated an ordinary cone siphon 0%", to the top of which is secured the air-pipe a, controlled by valve m, the latter, as

detachable-that is to say, its lower end is,

threaded at U and adapted to be screwed into an internally-threaded bushing secured to a siphon of ordinary construction in any desired manner.

The operation of my improved device is as follows, reference being bad to l ig. 1: The seat (1 being pressed downward, thus opening the valve 0 of the supply-pipe c (the stop-cock 0 being open) and allowing jthe water to flow into and fill the upper tank 3), the water will descend through tube (Z into the lower tank a, and by gradually filling the same the ball will be raised and the valve w, by action of the counterweight on the arm in, will close the air-pipe u. During the gradual filling of the tank a water will flow through drip-pipe f (regulating cock {1 being' open) into the balanced bucket 7', and as soon as the latter is filled the said bucket will tilt ovcrand discharge its contents into the flushingpipe m, thus creating a vacuum in the receptacle 7i, and thereby drawing the water contained in tank a through the siphon-pipe 7' into the said receptacle h and flushing-pipe m. As there is a constant inflow of water into the upper and lower tanks, respectively, the H ushlng will continue until the pressure on the seat (1 is released. The Water in the lower tank will rapidly descend until the ball, by the descending water, has raised the valve a, thereby allow-1 ing air to enter through tube a into the siphon-" pipe, and thus break the suction or siphoning force. The water remaining at that time in the upper tank will liow through pipe (.7, into the lower tank, which latter is thus again gradually filled. The water flowing through drip-pipe finto the bucket j will again fill said bucket, and when the same is tilted by the weight of the water asuction is again produced and the water siphoned through pipe 1' into the flushing-pipe until the ball has again raised the valve a: from its valve-scat, thus admitting air through tube a intothe siphon-pipe, whereby the siphon action is again broken. By this last described operation a final flush is obtained. From the above it can be seen that the upper tank serves as a kind of a storage-receptacle for the Water, (as there is a constant supply,) and even after the seat is released (the upper-tank being still filled) the said water will flow into the lower tank and will be sulliciont for the final flush.

When a continuous flushing is required, such as for public buildings, railroad-depots, (he. the devices shown in Figs. 2 and i are used. The cock 0' of the supply-pipe is left open, so as to allow a certain quantity of water to [low into the tank a. The water from said tank will flow through drip-pipe f into the bucket, fill the same, and tilt it over, thus producing a vacuum in the receptacle 7i and a suction in the siphon-pipe. The water is thus discharged through said siphon-pipe into the flushing-pipe until the water falling too near the bottom of the tank carries the ball down with it and thus opens the valve :10, admitting air into the siphon-pipe 7*, whereby the siphoning action is broken. The water will again rise in the tank, and after the valve is closed the heretofore described operation is re pcated.

From the foregoing it can be seen that the noise, so disagreeable during and alter the flushing of Water-closets, is fully avoided, as the air pa'ssinginto the siphoning-tube does not become mixed with the water.

It is obvious that various alterations can be made without changing the scope of my invention. Therefore I do not intend to limit myself to the precise construction shown and described, but

"What I claim as new, and desire to secure by Letters Patent, is
